The Iowa Department of Transportation has launched a new tool to show drivers the cost of clearing the state’s roads in the winter.

The “Winter Cost Calculator” estimates how much money has been spent keeping Iowa’s state-owned roads clear over the past 48 hours, the Iowa DOT reports.

According to the Iowa DOT website, the calculator can be used to see material, labor and equipment costs from clearing wintry roads. The tool also has a zoom feature that allows users to see the costs of maintaining roads in a specific metro or county.

The tool includes a legend indicating when high, medium or low amounts of resources have been used to keep the roads clear of ice and snow.
